some people i know get a very noticeable increase in hp and gas mileage from their tornado. unlike me, i have a 79 351m bronco and it hasn't increased anything for me? what do you people think about the tornado?

 

?

 

i tryed it in my car and din't notice a thing so i sent back and got my $70. I never checked for gas mileage.

 

anyone else?

 

From the other threads that I have read here, they mostly say that the biggest thing that they do is to lighten your wallet. No power, and no mileage. So, if a lighter wallet is what you are after, then use one. If not, take it back.

i took it off and im going to bring it back. it sucks that i had to have it special ordered so i am going to be getting 10% less money back. oh well. the extra $60 can be put toward something else for the truck.
